OpenSSL CHANGES
_______________
Changes between 0.9.2b and 0.9.3
*) New option -out to asn1parse to allow the parsed structure to be
output to a file. This is most useful when combined with the -strparse
option to examine the output of things like OCTET STRINGS.
[Steve Henson]
*) Make SSL library a little more fool-proof by not requiring any longer
that SSL_set_{accept,connect}_state be called before
SSL_{accept,connect} may be used (SSL_set_..._state is omitted
in many applications because usually everything *appeared* to work as
intended anyway -- now it really works as intended).
[Bodo Moeller]
*) Move openssl.cnf out of lib/.
[Ulf M�ller]
*) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
-Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
-Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
[Ralf S. Engelschall]
*) Various fixes to the EVP and PKCS#7 code. It may now be able to
handle PKCS#7 enveloped data properly.
[Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
*) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
copying pointers. The cert_st handling is changed by this in
various ways (and thus what used to be known as ctx->default_cert
is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
any longer when s->cert does not give us what we need).
ssl_cert_instantiate becomes obsolete by this change.
As soon as we've got the new code right (possibly it already is?),
we have solved a couple of bugs of the earlier code where s->cert
was used as if it could not have been shared with other SSL structures.
Note that using the SSL API in certain dirty ways now will result
in different behaviour than observed with earlier library versions:
Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
does not influence s as it used to.
Projected further changes:
In order to clean up things more thoroughly, inside SSL_SESSION
we should not use CERT any longer, but a new structure SESS_CERT
that holds per-session data, and CERT should hold only those
values that can have meaningful defaults in an SSL_CTX.
[Bodo Moeller]
*) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
from the internal representation. Various PKCS#7 fixes: remove some
evil casts and set the enc_dig_alg field properly based on the signing
key type.
[Steve Henson]
*) Allow PKCS#12 password to be set from the command line or the
environment. Let 'ca' get its config file name from the environment
variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
and 'x509').
[Steve Henson]
*) Allow certificate policies extension to use an IA5STRING for the
organization field. This is contrary to the PKIX definition but
VeriSign uses it and IE5 only recognises this form. Document 'x509'
extension option.
[Steve Henson]
*) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
without disallowing inline assembler and the like for non-pedantic builds.
[Ben Laurie]
*) Support Borland C++ builder.
[Janez Jere <jj@void.si>, modified by Ulf M�ller]
*) Support Mingw32.
[Ulf M�ller]
*) SHA-1 cleanups and performance enhancements.
[Andy Polyakov <appro@fy.chalmers.se>]
*) Sparc v8plus assembler for the bignum library.
[Andy Polyakov <appro@fy.chalmers.se>]
*) Accept any -xxx and +xxx compiler options in Configure.
[Ulf M�ller]
*) Update HPUX configuration.
[Anonymous]
*) Add missing sk_<type>_unshift() function to safestack.h
[Ralf S. Engelschall]
*) New function SSL_CTX_use_certificate_chain_file that sets the
"extra_cert"s in addition to the certificate. (This makes sense
only for "PEM" format files, as chains as a whole are not
DER-encoded.)
[Bodo Moeller]
*) Support verify_depth from the SSL API.
x509_vfy.c had what can be considered an off-by-one-error:
Its depth (which was not part of the external interface)
was actually counting the number of certificates in a chain;
now it really counts the depth.
[Bodo Moeller]
*) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
instead of X509err, which often resulted in confusing error
messages since the error codes are not globally unique
(e.g. an alleged error in ssl3_accept when a certificate
didn't match the private key).
*) New function SSL_CTX_set_session_id_context that allows to set a default
value (so that you don't need SSL_set_session_id_context for each
connection using the SSL_CTX).
[Bodo Moeller]
*) OAEP decoding bug fix.
[Ulf M�ller]
*) Support INSTALL_PREFIX for package builders, as proposed by
David Harris.
[Bodo Moeller]
*) New Configure options "threads" and "no-threads". For systems
where the proper compiler options are known (currently Solaris
and Linux), "threads" is the default.
[Bodo Moeller]
*) New script util/mklink.pl as a faster substitute for util/mklink.sh.
[Bodo Moeller]
*) Install various scripts to $(OPENSSLDIR)/misc, not to
$(INSTALLTOP)/bin -- they shouldn't clutter directories
such as /usr/local/bin.
[Bodo Moeller]
*) "make linux-shared" to build shared libraries.
[Niels Poppe <niels@netbox.org>]
*) New Configure option no-<cipher> (rsa, idea, rc5, ...).
[Ulf M�ller]
*) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
extension adding in x509 utility.
[Steve Henson]
*) Remove NOPROTO sections and error code comments.
[Ulf M�ller]
*) Partial rewrite of the DEF file generator to now parse the ANSI
prototypes.
[Steve Henson]
*) New Configure options --prefix=DIR and --openssldir=DIR.
[Ulf M�ller]
*) Complete rewrite of the error code script(s). It is all now handled
by one script at the top level which handles error code gathering,
header rewriting and C source file generation. It should be much better
than the old method: it now uses a modified version of Ulf's parser to
read the ANSI prototypes in all header files (thus the old K&R definitions
aren't needed for error creation any more) and do a better job of
translating function codes into names. The old 'ASN1 error code imbedded
in a comment' is no longer necessary and it doesn't use .err files which
have now been deleted. Also the error code call doesn't have to appear all
on one line (which resulted in some large lines...).
[Steve Henson]
*) Change #include filenames from <foo.h> to <openssl/foo.h>.
[Bodo Moeller]
*) Change behaviour of ssl2_read when facing length-0 packets: Don't return
0 (which usually indicates a closed connection), but continue reading.
[Bodo Moeller]
*) Fix some race conditions.
[Bodo Moeller]
*) Add support for CRL distribution points extension. Add Certificate
Policies and CRL distribution points documentation.
[Steve Henson]
*) Move the autogenerated header file parts to crypto/opensslconf.h.
[Ulf M�ller]
*) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
8 of keying material. Merlin has also confirmed interop with this fix
between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
[Merlin Hughes <merlin@baltimore.ie>]
*) Fix lots of warnings.
[Richard Levitte <levitte@stacken.kth.se>]
*) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
the directory spec didn't end with a LIST_SEPARATOR_CHAR.
[Richard Levitte <levitte@stacken.kth.se>]
*) Fix problems with sizeof(long) == 8.
[Andy Polyakov <appro@fy.chalmers.se>]
*) Change functions to ANSI C.
[Ulf M�ller]
*) Fix typos in error codes.
[Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf M�ller]
*) Remove defunct assembler files from Configure.
[Ulf M�ller]
*) SPARC v8 assembler BIGNUM implementation.
[Andy Polyakov <appro@fy.chalmers.se>]
*) Support for Certificate Policies extension: both print and set.
Various additions to support the r2i method this uses.
[Steve Henson]
*) A lot of constification, and fix a bug in X509_NAME_oneline() that could
return a const string when you are expecting an allocated buffer.
[Ben Laurie]
*) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
types DirectoryString and DisplayText.
[Steve Henson]
*) Add code to allow r2i extensions to access the configuration database,
add an LHASH database driver and add several ctx helper functions.
[Steve Henson]
*) Fix an evil bug in bn_expand2() which caused various BN functions to
fail when they extended the size of a BIGNUM.
[Steve Henson]
*) Various utility functions to handle SXNet extension. Modify mkdef.pl to
support typesafe stack.
[Steve Henson]
*) Fix typo in SSL_[gs]et_options().
[Nils Frostberg <nils@medcom.se>]
*) Delete various functions and files that belonged to the (now obsolete)
old X509V3 handling code.
[Steve Henson]
*) New Configure option "rsaref".
[Ulf M�ller]
*) Don't auto-generate pem.h.
[Bodo Moeller]
*) Introduce type-safe ASN.1 SETs.
[Ben Laurie]
*) Convert various additional casted stacks to type-safe STACK_OF() variants.
[Ben Laurie, Ralf S. Engelschall, Steve Henson]
*) Introduce type-safe STACKs. This will almost certainly break lots of code
that links with OpenSSL (well at least cause lots of warnings), but fear
not: the conversion is trivial, and it eliminates loads of evil casts. A
few STACKed things have been converted already. Feel free to convert more.
In the fullness of time, I'll do away with the STACK type altogether.
[Ben Laurie]
*) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
specified in <certfile> by updating the entry in the index.txt file.
This way one no longer has to edit the index.txt file manually for
revoking a certificate. The -revoke option does the gory details now.
[Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
*) Fix `openssl crl -noout -text' combination where `-noout' killed the
`-text' option at all and this way the `-noout -text' combination was
inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
[Ralf S. Engelschall]
*) Make sure a corresponding plain text error message exists for the
X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
verify callback function determined that a certificate was revoked.
[Ralf S. Engelschall]
*) Bugfix: In test/testenc, don't test "openssl <cipher>" for
ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
all available cipers including rc5, which was forgotten until now.
In order to let the testing shell script know which algorithms
are available, a new (up to now undocumented) command
"openssl list-cipher-commands" is used.
[Bodo Moeller]
*) Bugfix: s_client occasionally would sleep in select() when
it should have checked SSL_pending() first.
[Bodo Moeller]
*) New functions DSA_do_sign and DSA_do_verify to provide access to
the raw DSA values prior to ASN.1 encoding.
[Ulf M�ller]
*) Tweaks to Configure
Niels Poppe <niels@netbox.org>
*) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
yet...
[Steve Henson]
*) New variables $(RANLIB) and $(PERL) in the Makefiles.
[Ulf M�ller]
*) New config option to avoid instructions that are illegal on the 80386.
The default code is faster, but requires at least a 486.
[Ulf M�ller]
*) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
SSL2_SERVER_VERSION (not used at all) macros, which are now the
same as SSL2_VERSION anyway.
[Bodo Moeller]
*) New "-showcerts" option for s_client.
[Bodo Moeller]
*) Still more PKCS#12 integration. Add pkcs12 application to openssl
application. Various cleanups and fixes.
[Steve Henson]
*) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
modify error routines to work internally. Add error codes and PBE init
to library startup routines.
[Steve Henson]
*) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
packing functions to asn1 and evp. Changed function names and error
codes along the way.
[Steve Henson]
*) PKCS12 integration: and so it begins... First of several patches to
slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
objects to objects.h
[Steve Henson]
*) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
and display support for Thawte strong extranet extension.
[Steve Henson]
*) Add LinuxPPC support.
[Jeff Dubrule <igor@pobox.org>]
*) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
bn_div_words in alpha.s.
[Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
*) Make sure the RSA OAEP test is skipped under -DRSAref because
OAEP isn't supported when OpenSSL is built with RSAref.
[Ulf Moeller <ulf@fitug.de>]
*) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
so they no longer are missing under -DNOPROTO.
[Soren S. Jorvang <soren@t.dk>]
Changes between 0.9.1c and 0.9.2b
*) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
doesn't work when the session is reused. Coming soon!
[Ben Laurie]
*) Fix a security hole, that allows sessions to be reused in the wrong
context thus bypassing client cert protection! All software that uses
client certs and session caches in mul
